solar distillation of biomass? That sounds cool! Do you need a solar concentrator or something? I thought it required pretty high temperatures to get the gas out. I'd rather just light a fire :P

I suspect biomass isn't a viable large scale energy source because it grows so slowly. Ultimately it's powered by the sun. But it would certainly be great in the short term.

Go nuclear fusion! If they can get that finished it really could be water power, the end of all energy problems.
